Formula to find kinetic energy
WebKinetic energy is a scalar quantity, something with volume or magnitude. Mass is a scalar quantity, while velocity is a vector. The formula to calculate the kinetic energy of an … WebW net = W grav = − m g ( y f − y i), where y is positive up. The work-energy theorem says that this equals the change in kinetic energy: − m g ( y f − y i) = 1 2 m ( v f 2 − v i 2). Using a right triangle, we can see that ( y f − y i) = ( s f − s …
